What’s a good way to identify keyframes in ComfyUI?

So, I started to get into Animatediff Vid2Vid using ComfyUI yesterday and starting to get the hang of it, where I keep running into issues is identifying key frames for prompt travel.

Right now the only way I see is putting an image output into the workflow and pull the frame to a size of 10 images per row and start identifying them by hand. This works for shorter animations but feels pretty stupid and is getting rather unwieldy when I’m looking at 500-2000 frames.

Are there any custom nodes anyone is aware of that would help with that like an interactive timeline for the source video or how do you deal with it?
